Abstract (en)
The invention increases the fidelity of gas turbine engine module performance estimates that in turn enhance performance tracking and visibility. The methodology obviates input signal filtering since filtering may mask the onset and detection of a rapid measurement shift indicative of serious engine performance issues. The invention supports trend detection processes for timely detection, isolation and alerting of performance and engine system related faults. A system in accordance with the invention comprises a system input (102), an engine performance fault estimator (103) having first and second inputs (107, 108), an output (104), a time delay (105) coupled to the output (104) and a filter (106) coupled to the time delay (105) and to said second input (108).
